Demon Slayer: The Journey That Began When I Became Yoriichi's Sister

The scene, resembling something out of a horror movie, sent chills down Yuko's spine.

"That monster is, the Demon Slayer Corps' ghosts are, and Tamayo is that woman too. Why do you all have to stop me?!" Muzan's voice was filled with anger as he questioned Ikuko.

Yu Zi tilted her head: "You've killed so many people, why don't you ask yourself if you've done anything wrong?"

"All I wanted was to survive, what did I do wrong?!"

“Those who died because of you…” Suddenly, Yuko sighed, “So why do I have to explain to you?”

"You're completely out of your mind."

"You can live if you want, no one will care if you live to be hundreds of years old, but you shouldn't ruin other people's happiness."

"You hate the Demon Slayer Corps so much, don't you understand why the Demon Slayer Corps exists?"

"It's all because of you, Muzan, because you are the culprit who caused their family to be destroyed."

"In other words, the people you hate exist because of your evil deeds."

"I'm not going to listen to your nonsense anymore."

"You can go to hell now." Yu Zi pulled out the Shura Blade from the bottom of her foot and stabbed it through Muzan's face on the flesh wall.

"I've said it before..." Muzan's head was pierced, but that didn't stop him from speaking.

"Ok?"

"I want you to come to hell with me!"

"Accompany you? Sorry, I already have someone I like, and even if we went to hell, I probably wouldn't be on the same level as you." Yuko shrugged indifferently. "If you're really lonely, maybe you could find Kokushibo to accompany you on the road to the underworld?"

Yuko thought that if there really was a heaven and a hell, her damned older brother would definitely go to hell.

One hundred percent.

Even if Kokushibo finally realized his mistake, he couldn't undo the lives he had cruelly harmed over the centuries.

"I don't think he'd be so stubborn as to refuse you, his former boss."

Muzan was so angry he was losing his mind. He kept mentioning Kokushibo, that bastard Kokushibo!

It actually gave up the struggle because of that little bit of human emotion, even though it was a monster that could break through the boundaries of demons.

In Muzan's eyes, Kokushibo giving up resistance was the stupidest thing to do.

I never expected that my trusted subordinate would change so drastically in carrying out the mission after learning that his sister was still alive.

Becoming like those weak humans, hesitant and confused.

That's why they were defeated so easily.

At this moment, the internal flesh walls suddenly writhed, and a large amount of foam-like flesh extended out, seemingly intending to fill the space.

Yuko didn't want to be enveloped by this thing, so she pulled out the Shura Blade with a forceful pull.

But her hand paused as she felt resistance. Looking to the side, she saw two strange hands emerge from the wall next to Muzan's head, gripping her blade tightly.

At the same time, fleshy whips wrapped around Yuko's arms and legs, leaving her nowhere to escape in the confined space.

Just as Yuko opened her mouth to say something, Muzan spoke first, revealing a strange smile: "Guess whether I've completely neutralized Tamayo's poison?"

Yu Ziwei was stunned. Before she could understand what Muzan meant, she felt the sharp spikes extending from the flesh whip pierce her skin.

Are you really that unwilling to accept this? You still want to absorb her blood to gain power.

Just as this thought crossed her mind, Yuko unexpectedly realized that Tamayo wasn't absorbing her blood, but rather... injecting her own blood into her body.

This guy... wants to infect her with the toxins in his body?!

They even went so far as to exhaust their own physical strength.

Yuko could tell that Muzan's current state was a final burst of energy before death.

That's really... quite persistent.

Well, in a way, we're all the same.

"You don't actually think this level of poison can affect me, do you?" Realizing Muzan's intentions, Yuuko unleashed her Blood Demon Art in reverse, causing crimson ice crystals to slowly erode towards her.

A hint of disappointment flashed in Muzan's eyes as he looked at the Blood Demon Art, followed by a strange smile: "I know."

"what?"

You are very hungry.

"Nonsense, it's been daylight for ages. If it weren't for you, you bastard, I would have already had breakfast."

“You’ve controlled yourself very well, but a ghost is a ghost. No matter if you overcome the sunlight or not, you can’t change your carnivorous nature.”

"Look at this, do you really find this scene disgusting?"

A knowing smile spread across Muzan's face, as if he were certain that Yuuko wouldn't let such a good thing slip by.

"It seems that not only your values, but also your aesthetic sense are problematic."

"What?" Muzan was still unconvinced. "You didn't even have the slightest thought of eating me?"

"If you eat me, I..."

Yu Zi replied impatiently, "Are you alright? You already said your flesh and blood are poisonous, why would I eat it? Do you think I'm an idiot?"

Muzan remained silent.

The so-called toxins were just a topic he used to guide Yuko's conversation. In reality, after he broke them down, even the human-transforming drug would be unable to work on a second person.

Muzan wanted to see this woman lose her mind after being overwhelmed by the smell of blood.

He knew very well that ghosts were creatures that would go mad for flesh and blood.

What he wanted to see was the Demon Slayer Corps members doing their utmost to open the cage and discover that a monster was imprisoned inside.

Then, to their bewilderment, the monster slaughtered the entire Demon Slayer Corps.

He couldn't understand why Yuko was able to resist her instincts and maintain her humanity.

Could this be the miraculous effect of the blue spider lily?

Or was it Tamayo who did it?

As Muzan watched Yuko easily break free of his restraints, the veins on his forehead bulged as if his blood vessels were about to explode from the heat of taking a cold shower in the middle of summer.

From the very beginning, when he squeezed out the last bit of strength from his body, he did not use that strength to break down the human-transforming drug.

He knew very well that his physical strength could only provide temporary relief.

Muzan trapped Yuko inside his body, enduring excruciating pain as he tried to communicate with her.

But now, the pain seems to have reached an unbearable level.

He's about to turn back into a human.

"Why?" Muzan asked this question as his consciousness gradually became confused.

"Because you deserve to die."

This was the last human voice Muzan heard from this world.

Next, his will was overwhelmed by the excruciating pain all over his body.

Because there was no resistance, and with the dosage of three vials of the human-transforming drug, Muzan's transformation back into a human was faster than expected.

Muzan's face contorted in pain, and he opened his mouth wide, letting out a silent scream of agony.

A loud bang came from above.

Yuko looked up and a ray of sunlight shone down from above.
